I call it... not reading their Bible plainly.
Even metaphor in Scripture has indicators based on the context that it is metaphor.
This sounds to me like one can stop learning the treasures that contained in God's Word. There are depths to God's Word on levels that the casual reader will not always comprehend and it takes a continual seeking and knocking with God to find what He wants to say to us today with His Word. God's Word aids us in our walk with God. If one cuts off the Word, then they cut off their proper walk with God. We are not to forget His Word, and we are to continually meditate on His Word, and we must realize that His Word can revive (or give life), and that His Word can help to prevent us from sinning against Him, etc.
15 "I will meditate in thy precepts, and have respect unto thy ways.
16 I will delight myself in thy statutes: I will not forget thy word."
(Psalms 119:15-16).
47 "I prevented the dawning of the morning, and cried: I hoped in thy word.
48 Mine eyes prevent the night watches, that I might meditate in thy word."
(Psalms 119:47-48).
"his is my comfort in my affliction, For Your word has given me life."
(Psalms 119:50).
"But he answered and said, "It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God."" (Matthew 4:4).
"Your word I have hidden in my heart, That I might not sin against You."
(Psalms 119:11).
"How can a young man cleanse his way? By taking heed according to Your word." (Psalms 119:9).
4 "Hear, O Israel: The LORD our God is one LORD:
5 And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
6 And these words, which I command thee this day, shall be in thine heart:
7 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up." (Deuteronomy 6:4-7).
People can study the Bible and never get it because they are not truly seeking God on His terms. The Bible is all about Jesus, His redemption for us, and in living for Him. But to imply that studying the Word every day and wanting to apply it every day is not an ongoing life process until the day we die is also wrong. Man shall not live by bread alone. Do you stop eating food (i.e. bread)?
